Also sent this to wallke...If the inside of the cadence sensors is wet, dirty, or damaged, take a photo and contact Wallke Ebike Support. If it looks normal, line up the internal notch and pins (and external indicators) and press directly together without twisting. Besides, If you see an error code message on your Wallke X3 Pro?
Well... it started working again. However, I think I may know what happened. I'll tell you what I did and maybe you can use this information in the future.
I really want to make sure the bike and it's components have a very long life. So after a few miles and then about every 100 miles, I made sure to clean and lube the chain and other moving parts, including the bearings on the cranks. I think this was my misstep and possibly I got lube in the sensor. My reasons for that were:
1. I had just lubed everything the day before.
2. The motor worked fine with the throttle and the regen kicked in normally.
3. While stopped with 1 foot down and 1 on a pedal slightly rocking back and forth, the motor would start to kick in, making me think something was slightly impeding the sensor, like a residue on the contact areas??
These being the case, I believed that the last time I lubed around the cranks some of the lube worked its way into or around the sensor and prevented it from properly registering my pedal cadence. After a light wash, including a spritz of wd40, and an overnight dry, the sensor has, so far (about 50 miles), returned to full working order.
I am still curious if I am able to purchase a new cadence sensor? Just as a backup, in the event anything I have done, or might do, damages the current one.
